MacRumors notes that the highly-anticipated Walter Isaacson biography Steve Jobs began shipping at around 7:00pm ET to customers that pre-ordered it on Kindle, and at around 11:00pm ET to customers that pre-ordered it on iBooks. The electronic releases occurred just ahead of the 12:01am ET embargo date requested by the publisher.

My favorite anecdote from the 60 Minutes interview with Isaacson is when he discusses Steve's mortality with him. Steve first talks about the afterlife and how the wisdom that you've accumulated lives on, but then Steve pauses and goes on to say "but sometimes I feel that it's like an on/off switch. Click. And you're gone. And that's why I don't like putting on/off switches on Apple devices."

Bonus footage (that didn't air during the 60 Minutes broadcast) can be found at 60 Minutes Overtime. In the clips from Isaacson's interviews Jobs talks about the dominance of Facebook and how he admires Mark Zuckerberg.
